1884 create a PLT entry as a R_SPARC_WDISP30 reloc.
1885 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
1886 dynamic entries and the PLT if we saw a dynamic object.

5270 * som.c (som_begin_writing): New approach at dealing with holes
5271 in executables left by the HP linker. Does not rely on subspace
5272 alignments as subspaces are *NOT* guaranteed to be properly
5273 aligned in an executable (can you believe that!).
5275 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5277 * som.c (som_get_section_contents): New function. Do not try

5323 required by expansions. Set s and unset h when converting a reloc
5324 from undefined to section. Change handling of PC relative relocs:
5325 if against a section, they are correct in the object file, if
5326 against an external symbol they are pcrel_offset.
5327 (mips_relax_section): New function.
5328 (mips_relax_pcrel16): New function.
5329 (ecoff_bfd_relax_section): Define.

5413 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
5414 reloc, used in embedded PIC code.
5415 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
5416 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

5422 link_order loop. Use _bfd_generic_link_add_symbols_collect for
5423 add_symbls entry point.
5425 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
5426 counting relocs. Set SEC_RELOC flag for any section which has

5454 extended name table.
5456 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5458 Support for link_order types which generate relocs in order to
5459 support -Ur in the linker.
5460 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5461 from call to _bfd_generic_link_add_one_symbol.
5462 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5463 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5464 instead of bitsize to add_to_set call back.
5465 (_bfd_generic_final_link): Account for link_order relocs when
5466 allocating space for relocations. Handle them in link_order loop.
5467 (_bfd_generic_reloc_link_order): New function.

5472 argument from declaration.
5473 (_bfd_generic_reloc_link_order): Declare.

5484 (ecoff_bfd_final_link): Account for link_order relocs when
5485 allocating space for relocations. Handle them in link_order loop.
5486 (ecoff_link_write_external): Set the storage class of a defined
5487 linker created symbol based on the section it is in. Correct
5488 bfd_link_hash_weak case to use .sc rather than .st.
5489 (ecoff_reloc_link_order): New function.
5490 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5492 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5498 bfd_zmalloc. Free a pointer, not a union.
5499 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5501 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5503 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5505 * som.c (bfd_section_from_som_symbol): Only to do the value
5506 comparison for function symbols within executables.
5508 * som.c (bfd_section_from_som_symbol): Renamed from
5509 som_section_from_subspace_index. Pass in a native SOM symbol.
5510 For executables, iterate through the sections to find out
5511 which contains the symbol's address rather than using the
5512 symbol_info field. (symbol_info has a different meaning for
5513 dynamicly linked executables.)
5515 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5518 * som.c (som_begin_writing): Fix braino (one call to align
5519 space/subspace data was done unconditionally rather than
5520 just for executables.)
5522 * som.c (som_begin_writing): Align text in all executables to
5523 make HPUX kernel happy. Fixes strip/objcopy for shared
5526 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5528 * som.c (som_begin_writing): Account for alignment needs of
5529 subspaces too when writing executables. Never request a negative
5530 bss size. Fixes some problems with demand paged executables,
5531 still having problems with pure executables and shared executables.
5533 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5535 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5536 bfd_zalloc for rawptr, because later on we may call free, not
5539 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5540 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5541 * cisco-core.c: New file.
5542 * Makefile.in: Change accordingly.
5543 * configure.in: Recognize cisco_core_vec.
5544 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5545 * targets.c: Add cisco_core_vec.
5546 * bfd-in2.h: Rebuilt.
5548 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5550 * som.h (som_copyable_section_data_struct): New structure
5551 containing all the private section information which needs
5552 to be copied from input section to output section during
5554 (som_section_data_struct): Remove several fields now in
5555 som_copyable_section_data_struct. Make the space and
5556 subspace dictionaries be pointers (to save space when
5557 only reading objects).
5559 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5560 some references changed. Allocate a copyable data stucture if
5561 none exists. Store info into the copyable data structure.
5562 (bfd_som_set_subsection_attributes): Likewise.
5563 (som_is_space, som_is_subspace, som_is_container): New functions.
5564 Use these instead of directly accessing private data.
5565 (som_prep_headers): Allocate space and subspace headers here.
5566 Fill in some fields in the space/subspace headers from the
5568 (som_bfd_copy_private_section_data): Only copy the stuff
5569 that we really need to make objcopy and strip work. Allocate
5570 the copy_data structure for the output bfd before copying.
5572 * som.h (struct som_exec_data): New structure to hold exec
5573 info that must be preserved when running objcopy/strip.
5574 (struct somdata): Add new "exec_data" field and accessor
5575 macro. Add some comments on how the various fields are used.
5576 (som_section_data_struct): Make is_space and is_subspace bitfields.
5577 Delete unused subspace_index. All references now use the
5578 target_index field within the section structure itself.
5580 * som.c (make_unique_section): Delete unused declaration.
5581 (som_bfd_copy_private_bfd_data): New function.
5582 (som_object_setup): Allocate space for and save exec information
5583 that needs to be copied during objcopy/strip.
5584 (som_mkobject): Do not allocate space for a file header here.
5585 It is not used when only reading SOM objects.
5586 (som_prep_headers): Allocate space for and attach a file header
5587 to the output bfd. For executables, use the saved system_id
5588 value rather than trying to guess the right value. Do not abort
5589 wwhen setting file_hdr->entry* for executables.
5590 (som_begin_writing): For executables, set the exec_entry and
5592 (som_copy_private_backend_section_data): Always return a value.
5594 * libhppa.h (PA_PAGESIZE): Define.
5596 * som.c (SOM_ALIGN): Define.
5597 (som_begin_writing): If writing an executable, initialize all
5598 fields in the exec header to zero. Update fields in the exec
5599 header as sizes of loadable subspaces are computed. Carefully
5600 preserve alignments when building executables. Actually write the
5601 exec after all the fields are filled in.
5603 * Better long-filename handling. Reads SOM ABI compliant extended
5604 names, but doesn't quite write compliant extended names yet.
5605 * som.c (som_slurp_extended_name_table): Delete function. The
5606 generic code will handle things correctly.
5607 (som_slurp_armap): Seek to the beginning of the next member.
5608 (normalize): New function.
5609 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5610 name table into account when computing the file offsets in the
5611 SOM dictionary. Make sure to align to an even boundary.
5612 (som_write_armap): Initialize the checksum to zero.
5613 (ar_maxchars): Fix. Opps.
5615 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5617 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5618 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5620 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5622 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5623 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5624 * bfd-in2.h: Regenerated.
5626 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5627 this was also named trad_unix_bfd_copy_private_bfd_data.
5629 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5631 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5632 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5633 returns NULL, it is not an error. It's possible that some of
5634 these checks are not necessary (because the size can never be
5635 zero), but putting in the checks is the conservative thing to do
5636 in light of the fact that some of these malloc calls replaced
5637 unchecked alloca calls, in which a zero argument would work fine.
5639 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5641 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5642 duplicate definition.
5643 (osf_core_bfd_is_local_label): Define.
5645 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5646 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5647 failure indication, it merely means there are no relocs.
5649 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5650 after NAME, since SunOS /bin/cc can't handle it.
5652 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5654 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5655 From sukes@glue.umd.edu (Tasuki Hirata).
5657 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5659 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5660 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5661 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5663 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5665 * som.c (som_prep_for_fixups): Detect section symbols based
5666 on either the lack of private data or the symbol flags. Do not
5667 munge section symbol names anymore -- they no longer confuse GDB.
5668 (som_begin_writing): Leave space for an exec header if writing
5670 (som_slurp_symbol_table): Recognize both forms of section symbol
5671 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5672 section symbols to be the name of the section they represent.
5673 Debugging symbols begin with "L$0\001", not just "L$".
5675 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5677 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5679 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table

5772 cruft (like the #pragma alloca for AIX).
5773 In addition to that problem, the C alloca calls xmalloc, which

6132 raw size of the input section.

6692 bfd_som_set_subsection_attributes): Change parameters from char
6693 to int. Following a prototype with an old-style function definition

6803 undefined, look it up in the linker hash table.
6805 * aoutx.h (translate_symbol_table): The string index 0 has a

6830 The sparc (and possibly other?) NLM format requires a different
6831 way to write exports, so add a write_export field to the backend
6832 data (and set it to NULL for everything but the sparc).
